i have a DOHC ZC in my 86 CRX SI...heres the question...how can i tell if its OBD0 or OBD1? and where can i find a performance chip for it? the ecu has the numbers 37820-pg7-6640-401-116706
it is OBD0, however, the 86-87 Integra PG7 ECU (which you have) can't be chipped easily, if at all - you could convert the car to run the 88-89 Integra electronic ignition timing advance distributor and then use a chipped PM6 or PM7 ECU
that link is for chipping the 88-89 PG7 ECU, not the 86-87, which he has - they are not the same - the 86-87 D16A1 used a vacuum advance ignition timing, so the ECU has no ignition timing maps
